Description

Foul separator

Technical field

The present invention relates to a kind of foul separators.

Background technique

In cyclone type foul separator, dirt collection chamber or case are frequently used as main cyclone stage, foul quilt at this From the air flow separation flowed around dirt collection chamber.Clean air then passes through shield.However, since air is on the inside of collecting chamber Flowing, this meeting from the foul of air flow separation by volume again so that be drawn onto air stream.In order to reduce the level for rolling up suction again, Shield skirt section would generally be attached to the lower end of shield.The wall of shield skirt section towards dirt collection chamber extends outwardly, and effectively Dirt collection chamber is divided into two sections, top section and compresses lower section.Cross shield skirt section enter the foul of compresses lower section by Sucking air stream can be less rolled up again in shield skirt section.

Although the benefit in shield skirt section is obvious, they also result in some problems.Since skirt section is reduced in shield Gap between the wall of dirt collection chamber, biggish foul or clast can be maintained at the top section of dirt collection chamber.

Thus, it is desirable to which a solution, keeps the benefit with shield skirt section, but alleviates and led by shield skirt section The some problems caused.

Summary of the invention

The first aspect of the present invention provides a kind of foul separator, comprising: disengagement chamber is limited by outer wall, the separation Chamber has longitudinal axis；Into the air intake of disengagement chamber；And shield, including sieve, air, which can pass through sieve and flow out, to be divided From chamber.Shield further includes shield skirt section, is extended around an end of shield, and shield skirt section is fixed to shield at built-in edge Rest part, and have second, free edge.Skirt section is formed by deformable material, and including being formed on the surface in skirt section Multiple flanks.

As a result, skirt section can be effectively reduced in foul separator foul rolls up suction to air stream again, appoint without hindering What big dirt and dust passes through shield skirt section.Shield skirt section can be deformed to a position, at this location not in shield skirt section It is in the reduction of the gap size between shield and outer wall.Flank promotes shield skirt section back to unchanged shaped position, and makes skirt Portion more reinforces and elasticity, so that it is not damaged in any stage deformed.

Multiple flanks can around shield skirt section periphery it is evenly-spaced.Shield skirt section is thus around its entire periphery by equably Support, help reduce a possibility that any weakness is formed in shield skirt section.The evenly-spaced flank is also equably first Entire shield skirt section begin into unchanged shaped position, it is meant that roll up being effectively reduced for suction again around the foul of entire disengagement chamber and be implemented.

Flank can extend from the first built-in edge, and towards free edge along skirt section surface portion extend.Flank Length between the 50% and 100% of the extensible distance from built-in edge to free edge.Flank is thus near engaging portion Intensity and support are provided for shield skirt section, shield skirt section is fixed to the rest part of shield at this.This is subjected in deformation The place of maximum, force enhances shield skirt section, and helps to avoid the generation of any damage or tearing.If flank and less than freedom Edge is so remote, and shield skirt section can more easily deform at free edge, and big foul or clast are easier Ground deformation shield skirt section is come across it.

Shield skirt section can be fold, and each pleated portions can be positioned between two successive flanks.By making shield Skirt section fold, this promotes skirt section uniformly to fold in deformation, helps to reduce the possibility that fulcrum (pinch point) is generated Property, otherwise can be permanently deformed shield skirt section, or lead to other damages to skirt section.

Flank may be formed at shield skirt section on the surface of sieve.As a result, flank is provided in one direction than another The bigger biasing force in a direction deforms shield skirt section more far from shield sieve to shield skirt section, and compared with towards shield sieve It is easy to add.Do not expect that shield skirt section is deformed towards shield sieve during foul separator use, because this can effective ground resistance gear A part of sieve, and reduce the performance of foul separator.

In non-offset position, shield skirt section can be angled towards outer wall, and extends in disengagement chamber far from longitudinal axis. It is rolled up be drawn onto air stream again as a result, shield skirt section more efficiently prevents from foul in foul separator.

Shield skirt section can be deformed to the first deformation position, and wherein shield skirt section is by the longitudinal axis, remote towards disengagement chamber It is squeezed and deformed from shield sieve.When being in the first deformation position, the free edge in shield skirt section is foldable.As a result shield skirt section Its own can be aligned, to extend along the direction for being parallel to longitudinal axis.In the position, shield skirt section has and shield sieve phase Same outer diameter.

Shield skirt section can deform between the first deformation position and the second deformation position, wherein in the second deformation position, shield Overskirt portion is squeezed and deformed along the direction opposite with the first deformation position, is positioned against shield sieve.Therefore, shield skirt section can roll over The path of folded component or foul itself without stopping foul separator, may need by shield skirt section.

Flank is formed as increased thickness of the shield skirt material in the regional area for needing flank.As a result, being not required to Independent rib portion is attached to shield skirt material, because they are formed as the material in shield skirt section itself.It reduce dirty The assembling cost of object separator, and also reduce a possibility that flank can be separated from shield skirt section.

Foul separator may also include Wiping mechanism, for wiping shield during foul null clear operation.Wiping mechanism can Including polishing piece, sieve is contacted, and along the length of sieve during foul empties, axis is slided along longitudinal direction, and foul is pushed away To the opening of disengagement chamber.As a result, improved case null clear operation can be implemented, any foul quilt for ensuring to block around shield sieve It wipes and is discharged from foul separator.

During null clear operation, polishing piece can contact shield skirt section, and is deformed into the first deformation position above-mentioned.It is logical It crosses and makes the crumple of shield skirt section during null clear operation, otherwise larger dirty particles will be blocked by shield skirt section, and can pass through Shield and from foul separator be discharged.

Once contacting shield skirt section, polishing piece can contact the flank on skirt section first, start the folding in shield skirt section Dissolve shape.As a result when the power for being applied to it by polishing piece is squeezed and deformed, jackknife action prevents any fulcrum in shield skirt section In generation.Fulcrum may make shield skirt section to be permanently deformed, or shield skirt section is caused to be damaged.

The outer wall of disengagement chamber can be slided relative to shield, and outer wall may include polishing piece, extend radially inwardly from outer wall. As a result, the movement relative to shield sliding disengagement chamber is also used to wipe foul from shield sieve, without independent cleaning machine Structure, and thus this provides simple and cheap solution.

Outer wall can be removed from foul separator, and during outer wall removes, polishing piece slides over shield skirt section, while skirt Portion is in the first deformation position above-mentioned.Period is re-assemblied on outer wall to foul separator, polishing piece can be by shield skirt Portion is deformed to the second deformation position of middle restriction outlined above.Therefore, outer wall can easily from foul separator remove and again It newly is assembled into foul separator, if the more thorough cleaning of foul separator is required.Further, since polishing piece is protected in deformation Overskirt slides in portion, and outer wall can be removed and be re-assemblied, any part without dismantling foul separator.

Shield skirt section can be formed by molded rubber.
